The effect
Each copy of the C allele shifted the measure 0.0083 lower (95% confidence interval 0.0067-0.0099); p = 2 × 10−27.
How common The C allele had a frequency of about 26% in the people studied.
Where it sits Chromosome 16, band 16p13.3 — a missense change in CACNA1H.

What this is ClinVar's aggregate record for this position (as of its 2026-10-19 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.
What each result means
C/CTwo copies of the version the research linked to Height. That is the strongest link of the three results. A link in a study is not a diagnosis.
C/TOne copy of the version the research linked to Height. That is a smaller link than two copies.
T/TNo copy of the version the research linked to Height. This is the starting point the study compared everyone against.
rs4984636 is a single position in the genome, in or near the CACNA1H gene. Published research associates it with height. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.
What conditions is rs4984636 linked to?
On MyGeneLog this position is linked to Height. The research behind each link, and its sources, are set out on that condition page.
Does having rs4984636 mean I will get this?
No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.
Where does the information about rs4984636 come from?
GWAS Catalog, Nature 2022, PMID:36224396. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
